Compound of vanadium and selenium.



tions contain the oxidized vanadium as bases of the salts replacing one atom of hydrogen 1 srarns anion.

COMPOUND OE VANAIQIUM AND SELENIUM.

To all whom it may concern Be it known that I, FELIX VON OEFELE, a subject of the King of Bavaria, residing in the city, county, and State of NewfYork,"

have invented new and useful Improvements in Compounds of Vanadium and Selenium, of which the following is a specification.

It was known heretofore to combine oxidized vanadium compounds with oxidized selenium compounds; the products resulting from such combination contain'oxygen between the atoms of vanadium and selenium and are known as selenites of vanadiumoxids and their double salts ,with sodium, potassium. or ammonium. From the chemical formulas it is seen thatthese composiof selenious acid according to the formula H O Se O H One example vanadyl-selenite:

One oxygen atom in this case stays between the atoms of vanadium and selenium i. 0. forms a link between the atoms of vanadium and selenium.

The main object of my invention is to reduce compound bodies of vanadium compounds and selenium compounds so that no intermediate oxygen stays between the atoms of vanadium and selenium whereby new compound bodies of selenium and vanadium or selenium and vanadium with basic elements such example as potassium selenovanadites, potassium selenovanadates, sodium, or ammonium or lithium selenovanadites or selenovanadates are obtained.

The method of reducing is as follows: I combine oxidized vanadium compounds such as V. ,O vanadium monoxid, V 0

vanadium dioxid, V 0 vanadium trioxid,

mixture V. vanadiumtetroxid, V 0; vanadium pentoxid with oxidized selenium compounds as for example SeO selenium dioxid, or of selenium and nitric acid (Sc-{JINQQ with the value of cxtempo rancous.selcuiumdioxid and seleniumtrioxid in the usual way and expose the compound Specification of Letters Patent.

bodies to heat with or without the aid of other chemical reducing agents [as for example carbon compounds, sulfurous acid, or hydrochloric acid. It is essential to continue the application of heat until the reduction is completed.

The products obtained by this method of reducing combined bodies of vanadium compounds and selenium compounds are chemical compounds of vanadiumfand selenium, or, of vanadium and selenium with other elements in which vanadium and selenium are combined in such a Way that no intermediate oxygen stays, between their atoms. They represent the following complete group of compounds having definite chemical composition and are vanadium selenids as for example: V Se white vanadium selecase of alkali and earthy compounds or white crystalline salts for example KSeVO potassium seleno-vanadite.

I wish to state that if any oxygen is found present in the above enumerated compounds that it will never be a link between vanadium and selenium, that it has only chemical affinity to vanadium and therefore is not eX-' changeable between selenium and vanadium by any process.

Compounds of this class are directly soluble in the liquids of living beings or form soluble compounds when introduced into the body of a living being. 4

Having now fully described my invention I claim:

A chemical compound formed of vanadium and selenium, the atoms of which are in direct combination, without intervening oxygen atoms, said compound having the property of being directly soluble in the liquids of animate beings.
